4 Claims. *(01. 221-98) This invention relates to dispensing containers and has for an object to provide a novel container .iat will store the liquid and dispense an exact predetermined quantity of the liquid with minimum eifort, without measuring, and Without Waste.

A further object is to provide a container adapted to dispense mixed drinks, spirituous liquors, drugs and chemicals where accuracy is required.

A further object is to provide a liquid dispenser which will be formed of a few simple inexpensive and durable parts, andwhich will be neat and compact in appearance.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to Within the scope of the appended claims without departing from the spirit or sacricing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a cross sectional view of a liquid dispenser constructed in accordance with my invention.

Figure 2 is a front elevation of the dispenser.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, I0 designates a cylindrical vessel having gudgeons I I on the end walls which are received in bearing boxes I2 carried by inverted V shaped brackets I 3 which may be bolted as shown at III or otherwise secured to a table top I5. counter, or other support. The brackets I3 constitute supports upon which the vessel may be easily turned axially in either direction.

The vessel I0 is preferably formed of transparent material so that the liquid level in the vessel may be observed. A partition I6 is secured to the cylindrical wall of the vessel and extends substantially parallel with a diameter of the vessel. The partition coacts with the subtended arcuate wall in forming a measuring chamber. An inlet I'I is formed in the partition I6 above the liquid level in the vessel when the vessel is full and this inlet forms means through which the measuring compartment is filled when the Vessel is rotated clockwise to submerge the inlet below the liquid level in the'vessel. The partition may be formed of any desired material and in practice one end of the partitionmay be provided with a flange I8 which is riveted as shown at I9 or otherwise sealed liquid tight to the wall of the vessel. The inlet II may be formed simply by terminating the partition I6 short of the wall of the vessel and providing a flange 20 over which the liquid overows back into the vessel when the measuring compartment is too full. However the inlet may be formed simply by a slot or opening of any desired configuration formed in the partition.

The measuring compartment is provided preferably with spaced outlets 2| located at diierent levels on the wall of the vessel for selectively dispensing a predetermined measured quantity of liquid from above these levels in the compartment. Each outlet is preferably closed by a flap valve 22 having hinge ears 23 through which a pintle 24 carried by the outlet is passed to hinge the valve at the top to the outlet. A grip 25 projects forwardly from the outer face of the' valve and forms 15 means for opening the valve. An arcuate leaf spring 26 is secured at one end as shown at 2'I to the outlet and bears with its free end against the outer face of the flap valve to hold the valve closed v against the pressure of the liquid in the measur- 20 ing chamber.

A pair of perforated baie plates 28 is disposed within the vessel, these plates preferably having base fianges 29 which are secured by rivets 30 or other suitable connectors to the cylindrical wall of the vessel. The plates extend radially from the wall of the vessel and constitute agitatorsto thoroughly mix the contents of the vessel when the vessel is rotated to either limit of movement.

A yielding stop 3I is disposed on the outer face of the Ycylindrical wall of the vessel and preferably comprises a yoke 32 the bight of which is riveted as shown at 33 tothe cylindrical wall of the vessel. A pin 34 is slidably mounted in openings in the branches of the yoke and is provided at one end with a head 35 between which and the adjacent branch of the yoke a helical spring 36 is confined under tension. A nut 3l is screwed on to the opposite end of the pin and bears against the outer face of the adjacent branch of the yoke. Tightening of the nut will increase the tension of the spring 36.

A stationary abutment 38 is ly of the vessel in the path of the yielding stop 35. The abutment may be simply a U shaped bar which embraces the vessel longitudinally, the legs oi the bar being provided with flanges 33 which may be rigidly secured in any preferred manner to the supporting brackets I3. When the yielding stop 3| impinges against the abutment 38 the shock will be cushioned by the pin 35 yielding against the ltension of its spring- 36 and at the same time the Vessel will be vibrated by yielding of the pin 34 and assist in ridding the 55 arranged exteriorin the lling position.

Aoutlet as will be understood.

A stop is disposed on the cylindrical Wall of the vessel and is spaced from the yielding stop to engage the abutment 38 and limit rotation of the vessel in a counter-clockwise direction. The stop 40 may be simply an angle iron riveted to the wall of the vessel as shown at'4l.V

The vessel is provi-ded with4 a flanged iilling opening 42 which is closed by a cap 43 having an axi-al 'plug'44 which is tapered to snugly engage a similar taper formed on'the flange of the lling opening. The Vcap is threaded on to the flange of the illing opening as shown at45. The plug '.44 is provided with an axial opening 46 through which air may enter::the vessel to' permit the contents to flow out evenly and smoothly. The air inlet opening is'closed by a ball check valve 41 which is confined against aY tapered seat 48 4formed in the mouth of the opening,`b'y al helical spring 49 which is confined under tension between the valve and an annular Yshoulder 50 formed'Y atthe inner end of the air inlettopening. j

` An arm 5I projects upwardly from the abutment 38 Vand is provided with an offsetV Iinger 52 underneath which4 the ball 41 rides when .thev vessel is turned counter-clockwise to dis,- pensingposition. The nger is provided with a camsuriace 53'whichdepresses the valve 41 against the tension of its controlling spring 49 and holds the airrinlet 46 unsealed so that the contents ofthe. measuring chamber will flow evenly and Yfreely from the outlet 2|. When the vessel is turned in Ya clockwise direction the ballV check 'valve is carried away from the finger 53 and is immediately seated by the spring-49 to seal .theV air inlet 46 and prevent leakage of the contents of the vessel when the-vessel is Yturned clockwise to illl-` the measuring compartment. Y Y Y In operation the vessel is turned clockwise until the'neasuring compartment is submerged below the surface ofthe liquid in the vesselas shown by dotted lines in Figure 1. The measuring compartment. is quickly lled with a' predetermined ;volume 'of liquid #through `the inlet 11...The Vessel may now be-turnedr in a counter-clockwise direction to elevate the inlet I1 above theV surface of the liquid in the vessel. Any one of the Youtlets 2| may be opened to dispense a predetermined quantity of liquid above theparticular level controlledvby the selected YFrom theY above'description it is thought Vvthat the construction and operation Vof my invention will -be fully understood without further explanation.
